During a joint interview on Larry King Now August 21, the engaged Hit and Run costars once again took a stand for the gay couples who are being denied the right to marry in California.

"Once it's official and everybody stops appealing it the minute before it passes, we'll get married," Bell, 32, told host LarryKing, 78. Dating since 2007, Parenthood star Shepard popped the question in January 2010.

"I'll feel more comfortable having a party — or whatever we have, if anything — if half of our friends who are homosexuals [can celebrate]," Bell explained. "It's just kind of rude to invite everyone to a party for a rite not everyone can hold."

"We'll apply the appropriate paperwork for wills and security and such, but when he gave [the ring] to me . . . that meant more to me than proclaiming it in front of a group of people," Bell said. "That doesn't feel very significant to me. The moment that we shared when he proposed felt like the agreement."

Hit and Run, which Shepard also directed and co-wrote, features several of the couple's real-life friends, including Bradley Cooper, 37, Kristin Chenoweth, 44, TomArnold, 53, Joy Bryant, 35, Michael Rosenbaum, 40, and Ryan Hansen, 31. The film was released August 22.
